Ultra Small Package: MSOP8
High Isolation: 50 dB
Positive Control: 0/+3V to 0/+7V
Electrical Specications, T
A
= +25° C, Vctl = 0/+5 Vdc, 50 Ohm System
Typical Applications
The HMC194AMS8 /HMC194AMS8E is ideal for:
• Cellular/PCS Base Stations
• Portable Wireless
• MMDS & WirelessLAN
The HMC194AMS8 & HMC194AMS8E are low-cost
SPDT switches in 8-lead MSOP packages for use in
applications which require high isolation between two
RF paths. The devices can control signals from DC to
3 GHz and have been optimized to provide extremely
high isolation with minimal insertion loss in medium
and low power applications. On chip circuitry allows
positive voltage control operation at very low DC cur-
rents with control inputs compatible with CMOS and
most TTL logic families. RF1 and RF2 are reective
opens when “OFF”.
